Dormer, hip-to-gable, L-shaped and mansard conversions that add a bright, properly-finished new floor to your home.
A loft is often the most cost-effective room you'll ever add. We design the right conversion for your roof and your street, handle the structure and building regs, and finish it as a genuine bedroom suite — not an afterthought.
Added headroom and floor area with well-proportioned dormers.
Maximising space on semi-detached and period terraces.
A full new storey behind a mansard roof, ideal for conservation areas.
The simplest, most cost-effective option where headroom allows.

Most take around 6–10 weeks on site depending on type and finish.
Most can, subject to head height (ideally 2.2m+ at the ridge), roof structure and stairs. We assess this at survey.
